@Chris thanks for the heads up! Still "Dummy output" in the Sound Settings. Here are the steps I followed:
1. Downdloaded and installed the *.deb you pointed to: $ sudo dpkg -i *.deb 2. Copied the Intel SST firmware binary file to /lib/firmware: $ sudo cp skl_hda_dsp_generic-tplg.bin /lib/firmware/ 3. Rebooted, disabled Secure Boot and selected the new kernel (5.10.0-1025-oem). In dmesg, I see the following: $ dmesg | grep snd [ 10.027748] snd_hda_intel 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if info 0x040100 [ 10.027752] snd_hda_intel 0000:00:1f.3: Digital mics found on Skylake+ platform, using SST driver [ 10.051128] snd_soc_skl 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if info 0x040100 [ 10.051132] snd_soc_skl 0000:00:1f.3: Digital mics found on Skylake+ platform, using SST driver [ 10.051879] snd_soc_skl 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 10.103255] snd_soc_skl 0000:00:1f.3: Direct firmware load for 9d71-ACRSYS-ACRPRDCT-2-tplg.bin failed with error -2 [ 10.103261] snd_soc_skl 0000:00:1f.3: tplg fw 9d71-ACRSYS-ACRPRDCT-2-tplg.bin load failed with -2, trying alternative tplg name skl_hda_dsp_generic-tplg.bin [ 10.104296] snd_soc_skl 0000:00:1f.3: ASoC: Parent card not yet available, widget card binding deferred [ 10.129385] snd_hda_codec_realtek ehdaudio0D0: autoconfig for ALC256: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker [ 10.129388] snd_hda_codec_realtek ehdaudio0D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 10.129389] snd_hda_codec_realtek ehdaudio0D0: hp_outs=1 (0x21/0x0/0x0/0x0/0x0) [ 10.129390] snd_hda_codec_realtek ehdaudio0D0: mono: mono_out=0x0 [ 10.129390] snd_hda_codec_realtek ehdaudio0D0: inputs: [ 10.129392] snd_hda_codec_realtek ehdaudio0D0: Internal Mic=0x1a [ 10.129393] snd_hda_codec_realtek ehdaudio0D0: Headset Mic=0x19 Please see the attached log for full dmesg. ** Attachment added: "dmesg.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1915117/+attachment/5495892/+files/dmesg.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1915117 Title: [Regression] Audio card [8086:9d71] not detected after upgrade from linux 5.4 to 5.8 Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu version: 20.10 (updated from 20.04) Kernel: 5.8.0-41-generic #46-Ubuntu Manufacturer: Acer Product Name: Swift SF314-54 BIOS Revision: 1.11 Audio card: Realtek High Definition Audio Multimedia audio controller [0401]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d71] (rev 21) Summary ======= After upgrading from linux kernel 5.4 to 5.8, there is no more sound card available. However, if I select kernel 5.4 in GRUB, the sound card is available. Steps to reproduce ================== 1. Install 20.04 or 20.10 with a kenel 5.4 2. Check that sound output works as excepted (Settings > Sound > Output > Test) 3. Check that `alsa-info` command returns information 4. Upgrade kernel to 5.8 Expected results ================ Sound output still works. Actual results ============== 2. Sound card is available, and sound can be output to the internal speakers. 4. No more sound card detected (Sound Settings display "Dummy Output" in the list of output devices).
